【问题描述】：
我使用下面的代码将 .active 类添加到站点链接，但是当我单击菜单项或其中一个子项时，我需要在顶部的导航菜单上添加活动类。例如，如果我单击选项卡“admitere”或他的一个孩子，则选项卡“admitere”必须保持选中状态，直到我选择另一个选项卡。
I thought to create an array of all id of the menus and relative sub menus, wrapping the sub menu let's say within a span tag so when a child is selected check it against the url and if inside make the first menu relative tab选择。现在该站点突出显示了基于 Dreamweaver 模板制作的类别的第一个菜单选项卡，但我需要在模板系统之外创建一个动态菜单。
请帮我看看解决问题的正确方法。提前致谢。

我们是我的朋友，现在我可以拥有我需要的所有活动元素以及选择的第一个选项卡以记住我正在访问的菜单类别或子菜单。 当然，使用 jquery 代码可以更短。这是一个工作解决方案草案。 请发布改进。 谢谢
目前的问题是在第一次访问web时激活index.html，它只有在选择元素后才有效。
